I've got a 15hp go devil longtail with a smaller 3 blade prop.. Should I switch to a 2 blade, or just leave this one on there? It's only got about an inch to an inch and 3/4 space between the prop and cavitation plate.. Will i see a difference in performance or speed with a slightly bigger 2 blade?

Its slow as hell, and bogs in real thick stuff when it starts to dig a trench.. This is my first small longtail motor to own so Im not sure what to compare to..

Guess that's all i can do.. I jst don't wanna spend $250 for something that Wont give a drastic change in mainly speed and performance in the slop

I got a kohler 25hp and it came with a 3 blade on it. I got a 2 blade because they quit making the 3 blade for a longtail, but what I can tell you from my experience is that the 3 blade was much faster especially out in open water, but go-devil suggest you use the 2 blade if your running in mud the majority of the time. I hunt in a lake that is taken over by hydrilla and lilly pads with alot of deep water so I wish I could find another 3 blade just to get me there a little quicker, but I do like the 2 blade when im in the small shallow creeks.

You don'thave to spend $250 for a new prop! Check out this site, http://hillmarine.com/Weedless.html

I'd bet that 3 blade is worn, I dont know of anybody that makes em any more so a 2 blade will be about your only option.

lol that 3 blade is definatly on its last leg... and thanks bcoonass! I may have to invest in one of their props... do yall think the 9x5 will fit on my motor?

You will need 9x3!
